Karol G surprised her fans with J Balvin on Friday during her sold-out concert at MetLife Stadium in East Rutherford, New Jersey. The Colombian songstress is currently on tour promoting her album “Mañana Será Bonito.”

For the occasion, Karol G paired a pink crop top with a matching mini skirt, which both featured voluminous ruffles. She accessorized with a pair of matching thigh-high slouch boots and a colorful straw cowboy hat.

Balvin opted for an all-black ensemble, wearing a tank top and leather pants accessorized with an embellished western belt. He also added on sleek white sneakers and a pair of boxy frames.

“Mañana Será Bonito” marks Karol G’s first-ever stadium tour, which kicked off at Allegiant Stadium in Las Vegas in August. The singer has stopped in several major cities, including Miami, Houston and San Francisco. She’s set to perform in Chicago and Atlanta before her tour ends later this month.

Karol G’s fourth album came out in February. “Mañana Será Bonito” is the first Spanish-language LP by a woman to top the Billboard 200 chart.

Earlier this year, Karol G also appeared on the soundtrack for Greta Gerwig’s “Barbie,” performing “Watiti” in collaboration with Aldo Ranks. The star-studded album also features tracks from Charli XCX, Haim and Tame Impala.

While attending the Los Angeles premiere of “Barbie” in July, Karol G generated $1.9 million in media impact value for Emilio Pucci, wearing one of the brand’s designs on the red carpet.
